Surface active agents. Detergents. Determination of anionic-active matter hydrolysable and non-hydrolysable under acid conditions1 Scope This International Standard specifies a method for the determination, in detergents, of anionic active matter hydrolyzable and non hydrolyzable under acid conditions. This active matter includes alkyl sulfates and hydroxysulfates and alkylphenol and fatty alcohol ethoxysulfates. The mean relative molecular mass of the two types of active matter must be known or previously determined, if their content is expressed as a percentage by mass. If
